like letters on the drawing representing like parts.

This invention relates to looms provided with mechanism to replenish automatically the running filling and having means to detect filling absence on each pick, and arranged to arrest the operation of the take-up mechanism on each detection of filling absence.

My invention comprehends various features of operation found in such looms, and

is embodied in a so-called feeler loom, wherein by or through filling-exhaustion ind-icating mechanism filling replenishment is effected prior to complete exhaustion of the supply of filling in the active shuttle.

In United States Patent No. 833,796 granted to Northrop October 23, 1906, a com is shown and described provided with feeler' and two filling-detectors, and so arranged that by a change in the position, andv resulting operation, of a controlling or governing member the loom may be operated in av variety of ways.

My present invention relates to such a loom, and it also embodies a controlling or governing member adapted to be changed to vary the operation of the loom, the objects of the invention being a simplification of construction and arrangement in various particulars, and the obviation of some features which are found in practice to be attended with certain disadvantages.

The various modes of operation of the loom embodying my present invention may be classified in a manner similar to that adopted in the Nortl'irop-patent referred to, as follows A. Operating as an ordinary. fceler-loom, the feeler and the main or left-hand fillingdetector arranged to effect filling replenishment, the feeler acting prior to complete ex- 4 hausti'on of the running filling and the said detector acting when filling absence is detected thereby, both the main and the auxiliary, or right hand filling-detector controlling the take-up.

B. Operating with the feeler mechanism inoperative, but with the two filling-detectors operating asin (A). Conversion from A to B involves merely retaining the feeler mechanism inoperative.

C. Operating with the feeler mechanism operative, but with the two filling-detectors acting to effect stoppage of .the loom upon detection of filling absence, and to arrest take-up upon such detection. The conversion of the loom to operate in this case is effected by a change in the controlling or governing member, as will be explained.

D. By rendering the 'feeler inoperative when the loom is otherwise set to operate as in case C, so that the loom operates as a common double-fork loom, take-up being arrested and loom stoppage effected when the filling runs out or breaks.

The filling exhaustion indicating mechanism herein shown is substantially the same 'as shown in the Northrop patent referred to, and the double-detector devices are in the main such as shown in that patent, such differences as may exist in the structure forming the subject-matter of this invention being referred to hereinafter.

The various novel features of my invention, in construction, arrangement and operation will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure, l is a top plan view, centrally broken out, of a portion of an automatic filling-replenishing loom with one form of my resent invention embodied therein, the mec ianism being set for operation in accordance with the provisions of case A, abpvereferred to; Fig. 2 is a front elevation, centrally broken out, of a portion of the apparatus shown in Fig. 1, showing the connections between the two filling-detectors and the 1 connection between the replenishing mechanism and the feeler and the main or left-hand detector; Fig. 3 is an enlarged transverse sectional detail on the line 33, Fig. 1, looking toward the right; Fig. l is a similar view, but omitting some of the parts shown in Fig. 3, and with the controlling or governing member changed in position to change the operation of the loom to that specified in cases 0 or D. Fig. 5 a perspective view of the controllii'lg or governing member, detached.

The main filling-detector is located at the shipping side of the loom, and the auxiliary fillmg-detec'tor at the replenishing side, the

-rocking member, as the rock-shaft d incon nection with the feeler, (as will be made clear I auxiliary detector including afilling-fork g and its slide g longitudinally movable in the fixed guide g", the fork-tail being engaged by the'hook .w of an actuator or weft-hammer W Fig, 1, when the fork is not tilted, to thereby move the slide outward against its spring s Such movement of the slide swings outward an arm 2 having its hub 3 loosely mounted on the rock-shaft d, see Fig. 2, the inner end of the hub having a projection or lug 4 thereon which enters a notch 5 in a tubular shaft or sleeve 6, herein shown as looselymounted on and supported by the rock-shaft d. p

The coupling or connection between the arm 2 and the shaft or sleeve 6 causes the latter to be turned in the direction of arrow 300, Fig. 4, when the slide 'g is moved out ward, as will be manifest, and as will be explained hereinafter take-up is arrested thereby.

The cam for actuating the right-hand weft-hammer, in the Northrop patent referred to, was given a peculiar shape in order to prevent an extra replenishment of filling 2y or through the right-handfork detecting ling absence immediately after the-feeler had operated, and the somewhat quick, jerky motion of the weft-hammer due to the shape of the cam in practice has a tendency at tlmes to effect an unsatisfactory action of the mechanism. In my present invention I obviate the use of this irregularly shappd cam, as explained hereinafter, for the for -g is connected only with the sleeve 6, and not in any way with the controlling rock-shaft d, and consequently I obviate the quick, jerky motion of the weft-hammer.

In the Northrop patent the shape of the.

cam referred to is necessary in order to afiord time enough to stop the loom in case the filling. runs out on the same pick on which the fee'ler detected. By 111 present construction, connecting the-,aiixi iar-y fork mechanism with a rocking member,.as the sleeve 6, and using a separate hereafter) it is unnecessary to provide means acting through the same agency, viz: rockshaft d, whereby the right-hand fork and thefeeler may perform different functions. l

f moved outward in a guide f 2 by the wefthammer W when its hook to engages the fork tail, the outward movement ofthe slide against its spring 8 causing its shoulder f 3 to engage a lateral extension 7 on the upper end of an arm 8, herein shown as having its.

hub 9 loosely mounted on the rock-shaft d. Said hub 9 has on its inner end a lug 10, Fig. 2, to enter a notch 11 in the adjacent end of the tubular shaft or sleeve 6 thereby coupling the'latter and the arm to' move in unison.

The arm 8 hassecured to it a depending, rearWardly-projecting extension (P, Fig. 4, adapted when elevated to cause the arrest of the take-up mechanism (not shown) in substantially the manner described in United States patent to Northrop No. 789,291, dated May 9, 1905. That is, a lug d onthe extension may engage .the pawl-carrier p and move the same to disengage the pawl. from the ratchet in take-up mechanism of suitable character, such for instance as is shown in United States Patent No. 643,284. 2 From theforegoing it will beobvious that detection of filling absence by either detector f, or y, -will operate to turn the connection 6 between the arms 2 and8 in the direction of the arrow 300, Fig; 4, to thereby elevate the extension (Z and arrest take-u but it will be manifest that no operation 0 'the rock-shaft d to replenish filling can. be effected merely by such turning of the connection-6, for the latter is not in any way coupled with the rock-shaft d.

'As best shown in Figs. 3 and 4 the upper end of the arm 8 is shaped to present an outturned hook 12,. for a purpose to be described, and the fork-slide f X has on its outer side a boss 13 reduced in diameter-to present a horizontal stud 14, adapted to receive a removable fastenin ,such as a cotter-pih 15, Figf 1, the boss he shoulder f 3 on the slide.

The fillin -exhaustion indicating mechanism herein s own, see Fig.1, comprehendsa stand 9 on the holding late N, supporting a yieldingly-controlled side 12 having at its front end a shank 14 ears 18 on the slide sustaining the hunter 21 and the actuator 26 cooperating with the shank of the feeler proper 28 all substantially as in the Northrop Patent No. 833,796, hereinbefore referred to and operating as therein provided.

The tilting transmitter 34 fulcrurned at.

33 has its outer end bent at 37 and provided with .a cam slot (not shown) through which extends the controller 40 the inner end of the transmitter projecting loosely into a longitudinal slot 16, Fig. 3, in the rear end of the latch d? pivotally connected at its front end on the bifurcated up or end-of an arm (2 fast on the ,rock-sha t"d..., The

ing shown adjacent the actuator 26 will not cooperate with the controller 40 until the filling in the running shuttle is exhausted to a predetermined extent, which is indicated by the feeler 28 as it intermittently engages the filling in the shuttle, in well known manner, and up to the time of predetermined exhaustion the transmitter 34 is quiescent,and the latch (1 maintains the position shown in Fig. 3. When the predetermined filling exhaustion is attained the actuator engages and moves the controller 40 to tilt the transmitter, elevating the rear end of the latch (1 into the path of the head 10 on the weft-hammer W, and on the forward stroke of the latter the latch is pushed forward, acting through arm (1 to turn the controlling rock-shaft d in the direction of arrow 300, Fig. 4. Filling replenishment is thereafter effected when the shuttle reaches the replenishing shuttle-box B Fig. 1. Inasmuch as the arm (1 is fast on the rock-shaft d and has no connection with the sleeve 6 it will be manifest that filling replenishment by or through the fillingexhaustion indicating mechanism is not accompanied by arrest of take-up, and this is as it should be, for as there is no break in the continuity of the filling being laid there is no occasion for arrest of take-up. I

So far as the construction has been explained it will appear that neither of the filling-detectors can upon detection of filling absence, effect a change or replenishment of filling, but I have provided simple means whereby such replenishment can be effected by the main or left-hand forkf when desired, as for instance in cases A and B.

The operation of the loom is varied, in changing from cases A and B to cases C and D, or vice versa, by a controlling or governing member or device, shown separately in Fig. 5, and consisting of an elongated fiat body 17 having a longitudinal slot 18 and at its front end a rigid lug 19 is extended laterally from one side of the body, the latter in use standing on edge, as inv Fig. 1, 3 and 4. At its rear end the body is enlarged at 20 and shaped to present at one edge a shoulder 21, and on the opposite edge a shouldered lug 22, the shoulder 21 being nearer the front end of the body than is the lug 22. The edges of the enlargement 20 adjacent the shoulder anc lug are flattened at 21 22*, respectively, and parallel to the adjacent edges of the body. The controller is located. between the latch d and the adjacent side of the guide f for the main forkslide, the stud 14 on said slide entering the slot 18 and normally lying therein. at the front end of the slot, Figs. 3 and 4. When the loom is to be run in accordance with cases A and B the controller is so mounted that its lug 19 will extend to the left, Figs. 1 and 3, behind the upraised side 23 of the bifurcated arm d, with the lug 22 downturned, the edge 22 then resting on the attaching ear of the guide f A retainer,

such as a cotter-pin 15, in the stud 14, re-

tains the controller thereon.

. When the fee-ler operates and the latch (1 is pushed forward as explained it effects filling replenishment but has no influence over the controller, as its lug 19 has no engagement with the latch. If, however, the filling breaks and its absence is detected by the main fork f, the slide f thereof will bemoved outward by the usual cooperation with the weft-hammer W, and the stud 14 onthe slide will draw forward with it the con: troller, and the lug 19, engaging the part 23 of the arm (1, will swing the latter outward, turning the rock-shaftd to effect filling replenishment when the shuttle is in the shuttle-box B At; the same time the slide shoulder f 3 engages the lateral extension 7 on arm 8 and swings the latter outward, acting through the extension d to arrest takeup. If the main detector f does not detect filing absence first, but such absence is detected by the auxiliary detector: 9- on the pick of the shuttle to box B then the slideg is moved outward by its weft-hammer W the arm 2 is swung outward and the sleeveconnection 6 is turned. Such turning of said connection turns with it the hub 9 and arm 8, and thereby take-up will be anrested, but'there will be no movement whatever imparted to the main fork-slide f" nor to the rock-shaft d, as there is no connection with the arm 8. Hence there is no actuation of the replenishing mechanism, either directly elf-indirectly, by or through the auxiliary detector, its sole function being to arrest take-up when it detects filling absence, and to effect loom stoppage at such time in cases C and D. 4

When the loom is operating as in case A and the filling breaks or runs out on the flight of the shuttle to the replenishing. box B after the feeler mechanism has operated, the auxiliary detector 9 will detect such fail.- ure of the filling and will arrest take-up, but there will be no second operation of the replenishing -mechanism, as will be obvious, said. detector 9 having no operative connection with the controlling rock-shaft d, and unnecessary'denudation of the fillin -feeder is obviated without the use of specia means to prevent such denudation, as in the Northrop patent referred to.

Referring to Fig. 3 it will be seen that while the enlargement or shelf n of the knock-off lever is in the path of the lug 22 of the controller said lug is so far back that forward movement of the controller by the main fork-slide) is insufficient to bring the shoulder of the lug into. 006 )erative engagement with the shelf, to effect oom stoppage.

From the foregoing description it will be seen that when the controlling member 17 is set as in Figs. 1 and 3 either the filling-exhaustion indicatin mechanism or the main filling-detector v will effect filling-re lenishment, and that take-up is arreste when either the main or the auxiliary detector detects filling absence, thus fulfilling the conditions of case A. a To change from case A to case B, tliat is,

with the filling-exhaustion indicating mechanism out of action, but with-filling replenishment efiected automatically by or throil h detection of filling absence by the mainr etector, the filling-exhaustion indicating mechanism is conveniently maintained out of action by pushing forward-the feeler until a hole 100(see dotted lines Fi 1) in its shank 14 is exposed, and a suitabe pin is insert-- ed in the hole, maintaining the feeler device retracted and inoperative, 1

In case A and. case B there islno reat ob-' exhaustion indicating .Inechamsm. When so operating the loom conforms to the conditions of case 0, and this requires achange in the, osition of the controller or governlng mem er, with a subsequent change in. its mode of operation.

To change over to case C theretaining device .15 isw-ithdrawn, the controller is disengaged from one stud 14 and reversed or turned. upsidedown from-its position in Fig. 3 to that shown in Fig. 4:, audit is then replaced en the stud 1e and the retainer 15 aplied. By such reversal the lug 19 will proect tothe right of the controller, and immediately in front of the hooked upper end 12 of the ar1n8, as shown in Fig. 4, the shoulder 21 now being-downturned and the adjacent edge 21 rests upon the earf.

It will be seen that the shoulder 21 is very near the shelf cc of the knock-oil lever N and that very slight forward movement of ,the controller will act through said shoulder to o crate thelever N and effect release of the s ipper. v

Filling replenishment by or through the feeler device is'now effected in usual manner, when predetermined filling exhaustion is attained, the latch d being omitted in Fig. 4 in order to show clearly arts which would otherwise be hidden. If dime filling fails and its absence is detected by the main detector f the slide X will be moved outward, acting 60.

through the extension 7 to rock the arm 8 and arrest take-up, and at the same time the controller is moved outward, the shoulder 21 acting against the and causing the knockecfi lever .l l to release the shipper irom its holding notch to stop the loom. If

v the auxiliary detector 9 detectsfillin absence its slide g is moved outward, roc ing the arm 2 and turning the sleeve 6 in the directlon of arrow 300, Fig. 4, thereby swinging outward the upper, hooked end 12 of the arm 8. As the lug 19 on the controller is in front of said hooked end 12 the controller is moved forward and the'shipper is released, to stop the loom, while take-up is also arl rested.

It will beseenthat when the controller is moved forward by or through detectionlof filling absence by the detector .or fork g the slot 18 revents any movement of the main fork-sli e f to retract the fork from detecting osition,as the controller is moved forwar relatively to the stud 14, which traverses theslot. The controller isthus the connecting member betweenthe knock-oil lever N X and either fork-slide when set as in Fig. '4, whereas when set as in Fig. 3 the controller becomes the,connecting member between the main fork-slide only and the rockshaft d which governs filling replenishment.

When the controller is set as in Fi 3, its rear end cannot jum upaccidenta 1y because the upper end 0 the arm (P prevents anyldescent of .the lug 19. v

-When the controller is set as in 4 the hooked end 12 of arm 8 cooperates with the l Y19 and prevents its descent.

the loom is 0 eratin under the provisions of case C an the fee er has operated to effect fillin replenishment, su pose that the fillin brea s or runs out on the ick of. the shutt e to the replenishing side 0 the loom.

Under such conditions the auxiliarydetector .g detects the filling absence and its slide 'moves forward, thereby acting through arm 2, sleeve 6 and arm 8to-move the controller 17 forward to operate the knock-oil lever N stopping the 00m and arresting take-u Th1s prevents the continued operation of t e loom after replenishment with a pick'having;

only a partial filling laid therein,rwith thesimple mechanism herein shown, obviating the eculiar structure present inthe Northmp atent No. 833796 to effect a similar result.

To change the loom from o crating as ih case 0 to operate as incase l) exhaustion 1ndicating.mechanism is ,wit

held from operation by retracting the healer, .as in case B. The loom will then run simplyas a double-fork loom, breakage or running out of the filling arresting take-up and cans ing sto age of the loom. In either case B or case inoperative,- the transmitter 34 will be in normal position, with the rear end of the latch (2 out of the ath of the head w of the weft-hammer Various double-detector looin structures have heretofore been devised in which either detector operated to efiect filling replenish-v the fillingthe feeler being held retracted and Stafford-No. 805,497 dated November 28,

1905. None of these devices are necessary in connection with my present invention, because, as has been explained, it is impossible under any circumstances for the detector or fork at the replenishing side of the loom to initiate a replenishment of filling.

I have herein shown one practical embodiment of my invention, and it will be manifest that various changes or modifications in difi'erent'details of construction and arrangement may be made bythose skilled in the art,

without departing from the spirit and scope of my invention.
